The overall scheme of
system and
Moto Juji lead synchronous ECG machine adopts TI MSP430 series MSP430FG4616 as control core, and can conveniently realize ECG signal acquisition, processing, display and transmission. The system consists of five main parts: the preamplifier circuit part is used to enlarge the ECG signal; bandpass filter circuit part is used to filter noise from ECG signal frequency range; trap circuit is used to filter the 50Hz interference and the 35Hz EMG interference; bioelectrical data acquisition circuit portion for each ECG signal acquisition amplification after and send the data to the MCU; driven-right-leg circuit not only can inhibit the 50Hz frequency interference, but also according to the detection of ECG signal adjusting human body level, for ADC sampling; data processing display part is used for the filter algorithm to process data collection and real-time display of ECG waveform; network transmission part to the collected ECG data transmission to the hospital or the Centers for disease control, easy to understand the condition of the patient. System function in the liquid crystal display menu through the button to select finish, overall system block diagram is shown in figure 1.
